_xdc_runtime_System_printf__E unresolved symbols remain in DM3730

Other Parts Discussed in Thread: DM3730

Hi,

I am working with DM3730 and SDK version ti-dvsdk_dm3730-evm_4_02_00_06, in order to print DSP cycles measurements to the debugger i have used in the DSP code the function system_printf. As far as i understand using this function requires #include <xdc/runtime/System.h>.
In linkage i receive following error

Undefined symbol
error _xdc_runtime_System_printf__E

What may be the problem?

Hi Gabi,

I think you have an incomplete config script. If you are using CCS try right click on the marker and selects XDCtools -> Help and should get some guidance to solve the problem.

Also you look at the following link:

http://e2e.ti.com/support/embedded/tirtos/f/355/p/121153/431800.aspx#431800

where is described a similar issue.

Hi Tsvetolin,

Thanks for yor answer.
I am working with the Linux environment and not using the CCS for building the project, also i have seen the post you have sent a link to, but it didn't help me, i need specific help for the Linux environment.
Can you please advice?

Thanks,
Gabi

Hi Gabi,

The Rial-Time OS section of the E2E forum should be better place for investigation of the issue. Moving the thread there.

Hi Gabi,

You might not be linking with the xdc/runtime library. Can you share your makefile and generated linker script ? The generated linker script should be in the <CONFIG DIR>/package/cfg directory and should have a *.xdl extension.

Please share your app's *.cfg file also.

Best,

Ashish

Hi Ashish,

Basically my DSP code is based on the codec engine example videnc1_copy in

<codec engine>/examples/ti/xdais/dm/examples/

Attached please find the files requested.

I don't think you attached the correct configuration file.

It looks like you are missing the

var System = xdc.useModule('xdc.runtime.System');

in your configuration which would result in the linking of the missing library with the undefined symbol.
